of can rest upon the flanges 16 of thebarszl and 17 respectively withoutsagging under the weight of the liquid. Also due tothe weight I of thematerial used in forming the sheets the latter will stay in place sideby side without theneed of fastening means. The side walls forming thechannels 15 of the sheets 13 are perforated as at 18 in a staggeredmanner throughout the lengths thereof and are located at a distancespaced from the bottom of the channels-so that the body ofliquid mayflow from one end to the other of the distributor and trickle downthrough the perforations to effect the uniform distribution of theliquid over the entire filtering bed. It has been found that by thislocation ofithe perforations thesame are not apt to clog or stopup bymatter introduced with the waste but are kept open and clean as theliquid left in the trough between each discharge remains in the bottomof the channelsbelow. the openings or perforations thereof. I i Toobtain the best results of the liquid distribution the corrugated sheetsshouldbe supported in a horizontal plane-over the filtering bed. Toprevent undue spreading of the liquid at the point of discharge-from thefiltering trough use is made of shields: or antisplash plates 19 madeof'non-corrosive material, which together-with the vertical leg of the Tbar 4 serves to confine the: liquid therebetween and allow the sametospread evenly over the corrugated sheets.

From the foregoing it will be seen that I have provided' a distributorof' substantial and practical design, one which is easy to install andrequires but a minimum of attention to be kept in serviceableopera-tion- Further, due to the material from which the distributor ismade and due to its corrugated construction long life thereofissecured;

What is claimed is:

1. A liquid distributor of the class described, comprising a corrugatedsheet composed of asbestos fibers and cement compressed into a rigidbody, said sheet having the walls forming said corrugations formed withperforations.

2. A liquid distributor for a filtering bed comprising a pluralityof'substantially horizontally positioned parallel V shaped troughs, saidtroughs having their'side walls
